Jan.28 (GMM) If aesthetics mean anything, Ferrari will have a better year in 2015.

Last year, the F14-T - resembling a 'vacuum cleaner' according to some critics - was among the many cars of 2014 that sported an awkward look in deference to the sport's new rules.

Many of the responsible faces at Ferrari, having finished 2014 a distant fourth in the championship, have now departed amid the Maranello team's radical shakeup.

A survivor, however, is technical boss James Allison, the former Lotus designer and Briton whose newly-named SF15-T is his first full scarlet creation.

Ferrari insider Leo Turrini revealed this week that the vacuum-cleaner style nose of the 2014 is now gone ahead of the new season.

But Allison said the FIA's nose rule tweaks, made primarily for aesthetic reasons, is "not really so big a deal".

Overall, however, he revealed: "This year's car is certainly an awful lot better looking than last year's car -- prettier round the front, tighter round the back, and that makes for a nice car."

The 2015 Ferrari will be launched on Friday.

On the very same day, Ferrari customer Sauber will also unveil its 2015 car, the C34, on its official website.

The Swiss team also contradicted rumours the car may not be ready for the Jerez test on Sunday by announcing that Marcus Ericsson will be at the wheel in southern Spain for the opening day of the first winter test.
